STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 357,322, dated February8, 1887.

Application filed July 24. 1886.

T0 at whom it may concern:

Be it known that I, JOHN JOHNSON, of Ba ton Rouge, in the parish of EastBaton Rouge and State of Louisiana, have invented certain new and usefulImprovements in Stem finding and Setting -Watches, of which thefollowing is a specification.

This invention relates to certain improvements in the patent granted toD. H. Church, for a stem winding and settingwatch, No. 280,719, datedJuly 3, 1883, the improvements permitting the application of the windingand setting devices to any size of watch, large or small, and theconvenient inserting and removing of the movement into and from the ingand setting watch in which the winding and setting devices are actuatedby the winding-stem and an intermediate slide-piece in said stem, whichslide-piece actuates a fulcrumed and springactuated lever at one side ofthe main plate of the movement. The lever engages by an arc-shapedshoulder or projection a pin secured to the pivoted and springactuatedyoke that carries the winding and setting wheels, said pin passingthrough a slot of the main plate of the movement, so as to be in thepath of the fulcrumed lever.

The invention consists, secondly, of a recessed post and a V-shapcdspring, which is engaged at one end by said post, and which is connectedat its other end with the transmitting-lever of the winding and settingyoke, as will more fully appear hereinafter, and finally be pointed outin the claims.

In the accompanying drawings, Figures 1 and 2 represent a frontelevation of my improved stem setting and winding watch, shown with thedial removed and with the winding and setting devices, respectively, inposition for winding the springbarrel and for setting the hands. Figs. 3and 4 are rear elevations of my improved watch, showing the lever forsetting the pivoted yoke carrying the winding and setting wheels; andFig. 5 is a rear elevation showing the transmitting-lever in positionfor setting the yoke for winding only.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the winding-stem of my improvedstem winding and setting watch; 13, the winding-pinion of Serial No.20?,912. (No model.)

the same, which is turned by said stem, and B a slide-piece located inthe tubular stern of the winding-pinion, as will appear more fully inthe patent granted to D. H. Church, heretofore referred to. The lowerend of the slidepiece B rests on one arm of a fulcrumed angular lever,D, the other arm of which is engaged by a spring, D, which is preferablymade of fork shape, one end of the same resting against a fixedscrew-stud, b, while the other end of the same engages the recessed endof the lever D, as shown clearly in Figs. 3 and 4. The fork-shapedspring Dis attached at its apex to a post, 6, of the main plate of themovement.

That arm of the lever D which is engaged by the spring D is providedwith a short areshaped shoulder, d, concentric to the fulcrum of thelever D, said shoulder acting upon a pin, 6, that is secured to anoscillating yoke, E, at the other side of the main plate of themovement. The yoke E carries the usual winding and setting wheels, 6 c,and an intermediate crown-wheel, e which meshes with thewheels e and c",the yoke turning on the center portion of the crown-wheel 6 as customaryin stem winding and setting watches of this class. The pin or stud 0passes through a slot, f, of the main plate F of the watch-movement,said slot being made arc-shaped, corresponding to the motion imparted tothe pin 6 by the yoke E. The yoke E is acted upon bya spring, 6, to thetension of which it responds at the moment when the pressure of thelever D on the pin or stud e is released. u

WVhen the windingstemA is depressed and the slidepiece B pushed down,the lever D is oscillated on its fulcrum, so as to release the pin e andpermit the yoke to follow the tension of its spring 0*, and place thewindingwheel 6 into mesh with the gear-wheel of the spring-barrel, asshown in Figs. 1 and 3. In thisposition of the fulcrumed lever D tensionis imparted to the free arm of the spring D,

so that when the winding-stem is pulled out ICO wheels and be retainedin this position as the pin or stud e rests against the shoulder at ofthe lever, as shown, respectively, in Figs. 2 and 4. The spring D holdsthe lever D and the yoke E in this position until the winding-arbor A isdepressed again and the position of the yoke changed, so that itswinding wheel meshes with the gear-wheel of the spring-barrel.

WVhen the movement is removed from the ease, the winding and settingdevice is in mesh with the hand-setting wheels, which is also the casewhen the winding-stem is pulled out. When the movement is put back inthe case, the winding-stem is pushed in and the fulcrumed lever Dpressed downwardly, so as to release the pin or stud e and move the yokeE byits springin position for winding the springbarrel.

By arranging the shoulder dot the lover D, so that it} forms an arc of acircle, of which the fulcrum of the lever D is the center, the pin ofthe oscillating yoke is readily engaged by or disengaged fiorn thefulcrnmed lever D, so as to shift the yoke and the winding and settingdevices.

For the purpose of permitting the winding up of the spring-barrel andsetting the movement going while the same is removed from the case, thescrew-stud b has a recess at its base, which recess 1) engages theadjoining end of the forked spring when the screw-stud b is turnedtoward the spring. By turning the screw-stud b in opposite direction,the recessed base of the stud b carries the spring along and retains itin the position shown in Fig. 5. In this position of the spring D thelever D is moved sidewise, so that its shoulder clears the pin 0 of theyoke E, which latter is shifted by its spring 0, so that the gear-wheele is thrown into mesh with the winding-wheel of the spring-barrel. Themovement can then be readily wound and kept running as long as thescrewstud b retains the lever-spring Din position. When the movement hasbeen put into the case, the screw-stud b is turned on its 1 axis untilthe recess b releases the spring D,

quired. By thus controlling the position of the lever D and spring D thestem winding and setting device does not interfere in the least with themanipulationsof the movement and can be applied to movements of anysize.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with the winding-stem, a looseslide-piece located in the same, and the winding-pinion on said stem, ofa fulcrumed lever one arm of which is engaged by said slide-piece, aspring engaging the other arm of the lever, said lever having ashoulder, a pivoted and spring-actuated yoke located at the other sideof the movement, having a pin passing through a slot of the main plateinto the path of said shoulder, and winding and setting gear-wheels onsaid yoke, substantially as set forth.

2. The combination, in a stem winding and setting watch, of a fulerumedlever actuated by the winding-stem, said lever having a shoulder, anoscillating and spring-actuated yoke provided with the winding andsetting devices and with a pin that passes through a slot of the mainplate into the path of said shoulder, a fork-shaped spring which engagesby one end the fulcrumed lever, and a setting device that engages theother end of the forked spring and causes the setting of the yoke intoposition for winding the movement, substantially as set forth.

3. In a stem winding and setting watch, the combination of a fulcrumedlever actuated by the winding-stem,said lever having ashoulder, anoscillating and springactuated yoke provided with the winding andsetting gearwheels and with a pin that passes through a slot of the mainplate into the path of said shoulder, a fork-shaped spring of which oneend engages the fulcrumed lever, and a screwstud having a recessed baseadapted to engage the other end of the fork-shaped spring, substantiallyas set forth.

In testimony that I claim the foregoing as my invention I have signed myname in pres ence of two subscribing witnesses.

JOHN JOHNSON.
